Does the statement "can only be used to populate a label" above mean that I can not pull a number (elevation) from an external file? What if I change the number to be read as text? Can I use that in a calculation? My overall goal is to have a user input a point number, have Survey123 pull the elevation for that point number, do a calculation using a number inputted by user and show the new elevation. It seems simple enough but I can not get it to work.
